# How to Round Numbers in Python

To round numbers in Python, you can use the “round()” function. The round() is a built-in Python function that returns the floating-point number rounded off to the given digits after the decimal point.

### Syntax

``````round(number, digits)
``````

### Arguments

The round() method takes two parameters:

• number – the number that is to be rounded.
• ndigits (Optional) – the number up to which the given number is to be rounded.

### Example 1

``````# for integers
print(round(21))

# for floating point
print(round(21.9))

# even choice
print(round(21.4))
``````

Output ### Example 2

To round a number in given n digits, use the “round()” function and pass the ndigits argument.

``````print(round(21.1919, 2))

print(round(21.184646, 3))``````

In the above example, we have passed the second argument, which depends on how many digits you need to round up. In the first example, it is 2; in the second, it is 3. The best use of functions is handling the mismatch between fractions and decimals.
